take Tebow out of the equation. pretend he's not even on the roster. it still doesn't make sense to sign Manning for several reasons.

Manning is a veteran "rental" at this point. Denver is rebuilding. you don't waste money (in this case, alot of money) on expensive "rentals" that would sap your ability to rebuild while he's here.

It makes plenty of sense....

We have the cap room, we have talent, and if we add a player at the QB position of Manning's caliber we can be SB contenders.

Go tell Champ, Dawkins, DJ, and Dumervil we are in rebuilding mode after last season all those players tasted what the playoffs were like and they are hungry to win a SB. Adding Manning increases that chance.
